FOLDING STOOL.

SPECIFICATION forming part of Letters Patent No. 239,720, dated April 5, 1881.

Similar letters of reference in the several figures denote the same parts.

Our invention relates to improvements in folding camp-stools; and it consists in certain details of construction, hereinafter more fully set forth.

In the drawings, A represents the flexible seat, secured by fasteuings B to standardsG (J, which, in turn, are pivoted to a sliding block, D. The block D fits in a tubular support, E, to the lower end of which the legs F F are articulated, as shown. The block D is provided at its upper end with four pairs of lugs, (1 d, between which thelower ends of the standards G are pivoted upon pins 0, as shown. The sides of the block, below the lugs, are grooved, as represented at d, to admit the points of the standards below the pivots. The lower ends of the standards are pointed, and the points are slightly bent outw ard, as shown at 0, so that when the seat is expanded they will fit closely against the sides of the block D, within the grooves. By sliding the block D down in the tube E the points 0 will come within the-top of said tube, and will thereby be locked in position, with the standards expanded, as represented in Figs. 1 and 2.

The tubular device E is provided withthree pairs of lugs, e e, at its lower end, between which the legs. F are pivoted on pins f, the upper ends of the legs extending above the pivots and slightly projecting inward, as shown in Fig. 2 at 6, so as to enter slots 0 in the tube.

When the block D is raised to unlock the -standards C it thereby clears the ends ev of the legs and allows the latter to fold together; but when the block is depressed to lock the standards 0 expanded it enters between the upper ends of the legs F, and also looks them expanded. The raising and lowering of the block D in the sleeve E therefore serves to lock or unlock the arms 0 and legs F at one and the same operation. To prevent the block from being accidentally raised it is connected to the sleeve by a bayonet-fastening, consisting. of a slot, m, and pin a, whereby the parts are locked by sliding the block down and turning it slightly -to bring the pin under the shoulder 0.

The flexible seat is secured at its. corners between two angular flat plates, 1) b, by rivets 11 The lower plate, I). is provided with two lugs, b between which fit the ends of the arms 0, which are secured thereto by pivotpins 1). The flexible seat is thus firmly held, prevented from undue strain immediately at the corners, and is pivoted to its supports, so as to prevent cracking or wearing by contin ued use. The fastening is not only stronger, but also neater and handsomer, than that heretofore employed for similar purposes.

Having thus described our invention, we claim as new-- 1. The combination, with the block D, having the lugs 61 and grooves 01, of the standards G, pivoted to said lugs and provided with the pointed lower ends, 0, and the sleeve E, having slots at its lower end and lugs c e on each side of said slots, and legs F, pivoted to the lugs c and adapted to move in said slots, substantially as described, and for the purpose set forth.

2. The combination, with the flexible seat A I and standards 0, of the lower angular plates, 1), having the lugs b between each pair of which a standard is pivoted by a pin, 1), and angular plates b, the flexible seat being secured between the plates by rivets, or otherwise, passing through both plates and the seat, substantially as described, and for the purpose set forth.
